A simple string template function based on named or indexed arguments

Example

``js
var format = require("string-template")
var greeting

// Format using an object hash with keys matching [0-9a-zA-Z]+

greeting = format("Hello {name}, you have {count} unread messages", {
name: "Robert",
count: 12
})
// greeting -> "Hello Robert, you have 12 unread messages"


// Format using a number indexed array

greeting = format("Hello {0}, you have {1} unread messages", ["Robert", 12])
// greeting -> "Hello Robert, you have 12 unread messages"


// Format using optional arguments

greeting = format("Hello {0}, you have {1} unread messages",
"Robert",
12)
// greeting -> "Hello Robert, you have 12 unread messages"


// Escape {} pairs by using double {{}}

var text = format("{{0}}")
// text -> "{0}"

`

Compiling templates

string-template exposes two template compiling options for when you need the
additional performance. Arguments passed to the compiled template are of the
same structure as the main string-template function, so either a single
object/array or a list of arguments.

`js
var compile = require("string-template/compile")

var greetingTemplate = compile("Hello {0}, you have {1} unread messages")

var greeting = greetingTemplate("Robert", 12)
// -> "Hello Robert, you have 12 unread messages"
`

Passing a truthy second argument to compile will opt into using new Function
to generate a function. The function returned contains a literal string
concatenation statement, interleaving the correct arguments you have passed in.

`js
var compile = require("string-template/compile")

var greetingTemplate = compile("Hello {0}, you have {1} unread messages", true)
// -> greetingTemplate generated using new Function

var greeting = greetingTemplate(["Robert", 12])
// -> "Hello Robert, you have 12 unread messages"
`
